NGAD impression by Ar020

Little update. So this is the basic concept:
- Twin engined variable cycle engines.
- Two seater with WSO being the unmanned Flying Wingman operator.
- Side mounted IRTS and EOTS system with a vastly increased operating area.
- Front/rear mounted EOTS system with a wider spectrum due to shape and flush integration in fueselage.
- Innovating top mounted IR and Radar decoy launcher carrying small diameter missiles.
- B21 style leading-edge arrays AESA radar.
- Innovating stealth intake concept with priority for reducing the RCS from below.
- Innovative 2D thrust vectoring engine nossles for improved maneuverability.
- Innovative cooling system within the engine nossles.
- Top mounted missile bays for improved stealth missile launch.
- Mixed Delta/Flying wing concept a la B21 Raider.
- Innovating top mounted Chaff deployer.
- Interchangeble front mounted High energy laser system or Gun system.

I like it a lot, very cool design, U.S Air force take some notes on this one:)
 
Beautiful ! I like these innovative style intakes, dunno if that would work but sure looks good.
Only thing that bothers me are the markings. Regulation USAF roundels placement is only on top left wing, and on under right wing. With the top star branch pointing forward (it's pointing rear on the bottom ones here). Maybe smaller and just plain lighter grey would be good too, like this :

Just my 2€ cents.
 
Thanks for the nice words. Could you eleborate as to why the intakes wouldn’t work? Thats some great feedback and well spotted. I will fix it for the next ones.

Didn't say it wouldn't work, I said I don't know if it would work, as I'm no aeronautic engineer :D What is certain for me, is that it looks good.
 
Nice work. I think the dorsal missiles are probably more trouble than they're worth, the aero surfaces on the trailing edge look a bit odd. But seriously nice work.
 
I would like to offer some design feedback (also not an aircraft engineer)
In the sideview (12.pg) You can see the two pilots sitting, you should look at the nose and the eyeheight of the pilot in front. You can see that he can not look over the edge of the window.
Compare it to the F35 I have attached.
Just a minor thing I noticed on the otherwise nice design.

Nice collection of planes and cars. Heel mooi werk :)

Thanks for the feedback. Lots of fighterjets have the same problem. But it was a clear design choice. Its an evolution of the F35 Hud system which allows the pilot to see through the plane via VR visual enhancements. Hence all the frontal facing sensors and IR, FLIR, and shortwave infrared, camera systems a la F35 EOTS that all serve as one system for full 360 spectral vision all around the aircraft.

Bedankt!

I didn't spend time on things like pilots and stuff like landing gear which saves me a lot of time. I quite like your design tho.
 
Currently working on the Chengdu J-36. I will post some previews by Sunday.

Thanks :). It would be really interesting to be able to run an rcs simulation against its 3D model, but I don't have the required skills nor software to be able to do so, & I probably wouldn't be able to compensate you for your efforts even if you wanted to take the time to make this "concept" come to life, either, so...yeah. Don't worry about it, especially as this is probably only a one-time thing.

I can give you a simplified version of the base shape to run some aero tests.

This is a very sexy & dangerous CAD model, fit for a sci-fi movie like Stealth (2005), or videogames. :cool:

If you're interested in a more realistic version some day in future then some points to share here, whatever i understood in last 30 years of watching documentaries, articles, etc:
> The cockpit can be lowered a bit.
> The canopy size is too much. That much visibility is not required.
> You must've thought about BWB (Blended Wing Body), or narrow version of flying wing like B-2, B-21, but for narrow body the wing is too thick. Its longitudinal cross section should be like aerofoil.
> The exhaust are too much wide, big area. The area of intake, duct, engine inlet & exhaust are all related. You can take the area of engine inlet & flatten it like in F-117, but a morphing nozzle for afterburner.
> WSO is not needed to operate UCAVs. It can be done by voice interaction & screen input to the AI-UCAVs. Hence 2 seat is not required. Idea of virtual cockpit already shown in BAe Tempest, now GCAP.
> EOTS = IST + LD (Laser Designator). So EOTS on chin is enough. The F-35's DAS sensors perform IRST + MAWS functions. They're put on 6 axis already for spherical coverage. But you've done good job to increase their size means far more detection range. But the glass windows are rectangular, need to be trapezoidal.
> Missiles on top would be highly hazardous due to +ve G, cockpit obstructing launch envelope & air resistance hitting the angled launched missile sideways. SEPECAT Jaguar had top mounted pylon but its front area was clear of any obstruction & the jet had to launch while being very stable. It was not an agile jet. Moreover, the intake ducts need to be serpentine which would occupy the space you've used for top missiles.
> The intake side wall slant angle can be little more down.
> If you mount DEW then gun is obsolete. No gunfighter would dare come in DEW range. But the DEW also needs spherical coverage to defend from threats. So either 2 apertures (1 on belly & 1 on spine) can be put or 4 apertures on 4 corners ( 2 beside intakes + 2 beside engine exhausts).
> If you wanna retain rotary barrel gun then its barrel sould not be exposed.

If you implement all above changes then you might come very close to the real NGAD.:cool:

Thanks for the headsup. Really appreciate the feedback and suggestions. I will take this into my next design. I agree the wings seem to thick to create sufficient lift and control. You're the 2nd one who suggested removing the top mounted missiles.
